Zd. Liu et al., RAMAN POLARIZATION-SELECTIVE FEEDBACK SCHEMES FOR ALL-OPTICAL MICROWAVE FREQUENCY STANDARDS, Applied physics letters, 69(16), 1996, pp. 2318-2320
All-optical locking of the frequency difference between two laser diod
es onto a Raman transition is demonstrated. The properties of Raman-ty
pe polarization spectroscopy rue discussed and exemplified in the case
s of the 3.036 GHz Raman resonance of the Rb-85 D-2 line. The generati
on of a polarization-selective Raman resonant optical feedback ensures
the Raman optical locking of the slave diode laser onto the master os
cillator. (C) 1996 American Institute of Physics.
